The playback speed on youtube.com can be manipulated by using keyboard shortcuts < and >.
However, on my MacBook only the > for increasing playback speed seems to work while < does nothing.
What do I have to do, to make < work as well? Is there a way to decrease playback speed with another key?
Edit: According to the keyboard shortcut list on YouTube Shift+, and Shift+. should increase/decrease playback speed as well. Both combinations do not work either.
Edit2: As @Tir Dy pointed out, it works in Firefox.

. But I don't know how to change between sets on firefox or why only one of them works on Chromium. Before switching to Firefox I used to use an extension that allowed me to use any keyboard shortcuts to increase or decrease speed, but that has the problem that speed only increases in 0,05 intervals, so it takes you longer to change to the speed you want.
